Original question:

DRV2605L-Q1: Can one DRV2605L-Q1 support two or more identical ERMs?

DRV2605L-Q1: Do we have recommended LRA vendor or LRA P/N to use along with DRV2605L-Q1?

Hi team,

It's the 1st time for my customer to design a display which can automatically rotate the content displayed when the screen is rotated.
They are evaluating DRV2605L-Q1, but they don't have much idea on which LRA to choose.
Do we have any recommended LRA P/N that can be used with DRV2605L-Q1?
Thanks.

    Hello, 

    A lot of LRAs can fit with our device, and the type of LRA chosen is typically dependent on the location and kind of vibration wanted. The LRA frequency range supported by this device is 125 - 300 Hz and the min impedance is 8 ohm, so I recommend reaching out to LRA suppliers with these specs and the specs of the application. I believe with that they would be able to provide some good LRA recommendations. Such companies could be TDK or vybronics. 

    We also have an EVM for this device that has an on board LRA and ERM if they would like to evaluate them. The board also allows for easy testing of external actuators.
